Natus Vincere vs Nemiga Gaming
Well, Natus Vincere are gonna play tonight with stand-in (without their midlaner) so it's a great chance for Nemiga to punish Ukrainian team. Though Natus Vincere started season decently, they are still unstable.
Nemiga is lower by all components of the game, but slightly. Their advantage is in the core player Zitraks, he recently got top-1 position on EU matchmaking and can carry the game 1v5.
So, don't need to risk too much - medium stake here, chances are equal imo
